Those look just like the leather loafers I used to wear driving!!! Notice the placement of his foot on the edge of the brake pedal.

The commentary I heard when they were talking about the difference between Schumacher and Senna was that he used the pedal pumping to keep the car at the limit. Notice, no left foot braking. On the telemetry thing it looked like Barrichello did similar pumping through the corner.
